Knowledge about osteoarthritis: Development of the Hip and Knee Osteoarthritis Knowledge Scales and protocol for testing their measurement properties

ABSTRACT:

Objectives

1) Develop unidimensional instruments to measure osteoarthritis (OA) knowledge among people with hip or knee OA, and 2) assess the structural validity, internal consistency, cross-cultural validity/measurement invariance, test-retest reliability, and measurement error of the Hip Osteoarthritis Knowledge Scale (HOAKS) and the Knee Osteoarthritis Knowledge Scale (KOAKS).

Methods

Draft HOAKS and KOAKS were developed and refined following best-practice (COSMIN) guidelines with involvement of consumer research partners. Measurement properties of the HOAKS and KOAKS will be assessed through an online survey. The survey will include the novel HOAKS or KOAKS, the current short form of the Hip or Knee injury and Osteoarthritis Outcome Score (HOOS-12/KOOS-12), and items
